Abstract: Soil loss expectation and possible relationships among soil erosion, riparian vegetation and water quality were studied in the São José dos Dourados River basin, State of São Paulo, Brazil. Through Geographic Information System (GIS) resources and technology, Soil Loss Expectation (SLE) data obtained using the Universal Soil Loss Equation (USLE) model were analyzed. For the whole catchment area and for the 30 m buffer strips of the streams of 22 randomly selected catchments, the predominant land use and habita… Show more

“…Some studies show that, to protect aquatic biodiversity and assure the ecological processes in lotic environments, it is necessary to protect most of the river basins, since only the restoration of riparian zones close to the rivers is insufficient to improve the integrity of the whole system (Harding et al, 1998;Teels et al, 2006 andauthors therein, Lévêque et al, 2008). If protection of most of the river basins is not possible in heavily agricultural basins, wooded riparian cover could be effective in maintaining and improving fish community composition in streams (Stauffer et al, 2000) and such conclusions are valid here when one considers that most of the soil of the studied region is intensely used for food or fuel production (Silva et al, 2007). Nevertheless, in many regions not even the riparian zones are protected, as pointed by Silva et al (2007) in studies which demonstrate that some areas of the Southeastern region of Brazil has less than 25% of its riparian areas with forests.…”

In the long term, the environmental pressures coming from the absence of riparian zone protection, particularly the river bed covering by thin sediments, the habitat volume reduction and the development of rooted aerial macrophytes (Bunn et al, 1997), drive the streams to a condition similar to that observed in DEG.…”
